In an open letter to Prime Minister Manmohan Singh, senior Bharatiya Janata Party leader Arun Jaitley has urged him to put an end to the alleged misuse of investigative agencies by the Congress-led United Progressive Alliance government.

In his letter, Jaitley has cited examples of various cases, including the Sohrabbudin and Ishrat Jahan encounters, to illustrate his point.

The Leader of Opposition in Rajya Sabha has also alleged that the UPA was misusing both the Central Bureau of Investigation and the National Intelligence Agency as it cannot 'fight the BJP and Narendra Modi politically'.

The government has been misusing investigating agencies like CBI, IB and NIA to settle scores with the Bharatiya Janata Party (BJP) and its Prime Ministerial candidate Narendra Modi as it has realised that it cannot fight them politically, Rajya Sabha leader of opposition Arun Jaitley has alleged in a letter to Prime Minister Manmohan Singh.

Ordinance Cong ploy to save own leaders: BJP

In the 15-page letter to the Prime Minister, the Leader of the Opposition in Rajya Sabha has said that the Congress is targeting Modi and his former home minister Amit Shah for the past few years.

"The Congress strategy in the face if its depleting popularity is clear. Congress cannot fight the BJP and Narendra Modi politically. Defeat stares them in the face. By misuse of investigative agencies they have so far tried various methods of falsely implicating Modi and his former Home Minister Amit Shah," Jaitley said in his letter.

Congress misusing CBI, constitutional authorities: Rajnath Singh

Jaitley had written the letter on September 27 but the BJP was silent about it as the Prime Minister was on a visit to the US.

CBI will fight upcoming polls, not Congress: Modi

Prominent "examples" of misuse of probe agencies by the government that have been cited by Jaitley include the three encounter cases of Sohrabuddin, Tulsi Prajapati and Ishrat Jahan. He also states in his letter that former Home Minister of Rajasthan Gulab Chand Kataria was arrested in the Prajapati encounter case due to the role of the investigating agencies.

Similarly, former Rajasthan PWD Minister Rajinder Rathore was named in alleged fake encounter of local mafia Dara Singh.

Referring to the Sohrabuddin encounter case in his letter, Jaitley said, "The probable purpose of the CBI in this case was to try and implicate the political establishment of Gujarat, setting aside the pretence of federal character of India's governance. The CBI targeted Amit Shah with the ultimate desire of implicating Modi."
